represent only that quantity of units from which the sample was drawn
and shall not be construed to represent any prior or subsequent quantities
presented for inspection. Homogeneity shall be considered to exist
provided the lot has been produced by one manufacturer, in one unchanged
process, in accordance with the same drawing, specification or revision
thereof. Changes to either the process, specification or drawing not
affection safety, performance, interchangeability, or storage, as
determined by the Government inspector, shall not be deemed to alter the
homogeneity of the lot. Inspection lots shall comply with MIL-STD-105
and shall be numbered in accordance with MIL-STD-1168. Each loaded
igniter lot shall consist of:
a. Parts from three lots or less from one interfix from one
manufacturer.

tractually scheduled for production during the contract period nor more

month of the contract period, but never less than 1201 assemblies.
